Griffin fan wiring

[408maro]

Got a dual fan radiator setup from Griffin and curious how you'll with a psi conversion kit or ls in general hooked it up?

Psi recommends to hook the relay grounds to designating psi wires.

However the fans come with a sender which I don't want to use and rather go strictly off the ecm to control..

Any thoughts ?

My Griffin dual fan setups relays are ground triggered by my Holley HP ECU.

thank you, thats pretty much the same that PSI told me this morning via email.

they said use the relay grounds and connect those to the ecm wires designated for fans
